Retinal detachment surgery is divided into internal and external approaches. Generally, the surgery takes about one to two hours, or two to three hours.

One method involves compressing from the outside of the eardrum, pushing the eardrum inward to reattach the retina, while the other involves operating from inside the vitreous body outward to adhere the retina to the choroid. The recovery time for these surgeries generally reaches a stable condition from one to three months. The duration of the surgery depends on the complexity of the condition; it can be as quick as just over half an hour in simple cases, or up to two to three hours in complex cases. Postoperative vision recovery primarily depends on the duration and morphology of the retinal detachment, as well as the proliferation conditions of the detached retina and the vitreous body.
